Abstract
Abstract Novel fabric softening compounds of the formulae <IMAGE> +TR <IMAGE> wherein R1 and R2 are independently selected from the group consisting of aliphatic radicals containing from about 8 to about 22 carbon atoms, R3 and R4 are independently selected from the group consisting of hydrogen and methyl, R5 is selected from the group consisting of hydrogen and aliphatic radicals containing from about 8 to about 22 carbon atoms, x and y are independently integers from 1 to about 20, and z is 0 or 1, are disclosed. Also disclosed is a method for conditioning textiles utilizing said compounds.
